We considered the importance of low frequencies in seismic reflection data for enhanced
resolution, better penetration, and waveform and impedance inversion. We reviewed various …

The presence of noise in towed marine seismic data is a long-standing problem. The various
types of noise present in marine seismic records are never truly random. Instead, seismic …

Introduction to Petroleum Seismology, second edition, provides the theoretical and practical
foundation for tackling present and future challenges of petroleum seismology, especially …

Seismic amplitude variation with offset (AVO) inversion is well-known as a popular and
pragmatic tool used for the prediction of elastic parameters in the geosciences. Low …

ABSTRACT A dual-sensor towed streamer records the pressure and vertical component of
particle motion associated with the incident wavefield that may be used to separate the …

Methods for wavefield injection are commonly used to extrapolate seismic data in reverse
time migration (RTM). Injecting a single component of the acoustic field, for example …

We evaluated a solution to seismic deghosting that deghosts the low-frequency components
of the seismic pressure data. In an approximation that neglected the dependence on …

Acoustic Gaussian beam migration is an attractive imaging method because it is flexible with
input geometry, efficient, and accurate in imaging multipath arrivals. However, one of the …

Accurate surface-related multiple removal is an important step in conventional seismic
processing, and more recently, primaries and surface multiples are separated such that …

ABSTRACT A marine source generates both a direct wavefield and a ghost wavefield. This
is caused by the strong surface reflectivity, resulting in a blended source array, the blending …
